Abstract

L'invention concerne une extrudeuse comportant un dispositif de modération de la température. Dans cette extrudeuse comportant un fourreau 1 muni d'un perçage 2 destiné à loger la vis de l'extrudeuse et une bride de raccordement 8, permettant le raccordement de deux éléments de cylindre entre eux, il est prévu des ensembles de perçages périphériques 15 ménagés côte à côte dans le fourreau 1 et qui sont raccordés, pour former un canal de refroidissement s'étendant en formant des méandres, par des canaux annulaires 3, 4 et des perçages radiaux 7, 10, 14 à une admission 11 et à une sortie pour le fluide de modulation de la température. Application notamment aux extrudeuses pour le traitement de matières thermoplastiques et de caoutchouc.The invention relates to an extruder comprising a temperature moderation device. In this extruder comprising a sheath 1 provided with a bore 2 intended to accommodate the screw of the extruder and a connection flange 8, allowing the connection of two cylinder elements together, sets of peripheral bores 15 are provided side by side in the sheath 1 and which are connected, to form a cooling channel extending in meanders, by annular channels 3, 4 and radial bores 7, 10, 14 to an inlet 11 and to an outlet for temperature modulation fluid. Application in particular to extruders for the processing of thermoplastic materials and rubber.
